Keyboard keystrokes continue to be held when packets are lost by congestion or unstable connection / Improve the last bit of keyboard latency overall while accommodating unstable connections

[ehfd]

Keys continue to be held when packets are lost by congestion or unstable connection. This is because key presses are sent by signals when they are pressed and when they are down.

The above is a good solution to this problem, to send key-repeat packets continuously when a key-press is made and when such packets stop, un-press from the host.

Reopening in order to consult other projects and reevaluate the solutions.

PRs have been reversed.

Various considerations including asynchronization are required.

main...PMohanJ:selkies-gstreamer:keyboard-linked-list should be brought back after the v1.6.0 release. It must be ensured that there is no introduced latency to keystrokes.

In short, this is the reverse of this commit (ignoring README.md and gstwebrtc_app.py).
